[Elecraft] K3 MCU download /

2022-04-03 Thread hp via Elecraft
Here is one line from an EA6 message about a K3 he just purchased . 

Elecraft K3 is stuck at MCU LD and need to be sent to Italy to Elecraft 
Official Service to recover it. 

Are there any tricks to recover without sending it to a service site ?? 

I have told him how to subscribe to the reflector and gave him a link to the 
archives 
but maybe someone has a quick answer which I can forward to him .

Along with Dave's notes -If you want to study PIN diodes in RF switch 
applications - go to Ma-Com and download AN3022 and AG312 

https://www.macom.com/ 

>Applications and search by the app note

[Elecraft] KPA500 receive loss

2021-06-05 Thread HP via Elecraft
Just noticed this evening that on 160 I lose about 6 dB of rx level (noise and 
signal ) when I go from STDBY to OPER. On 40 maybe a dB or so , on 20 no change 
-- On160 almost always am using RX antenna so am not going thru the KPA but 
this evening had Tx ant on RX . 

Maybe has always been that way and just never noticed ???
